Letters .Patent No. .91,962,41ated June 29,V 1869.

ILIPROVED MODE OF UTILIZING TIN-PLATE CUTTING-S 'IN THE MANUFACTURE 0F IRON A ND STEEL.

The Schedule referred to in these Letters Patent and making pan, or v ie same.

T0 Awho-m, it 'may conce/rn:

Be it known that I, D; D. PARMELEE, @fue city,

county, and State of N ew Yor.k,^have invented a new and useful process by which. refuse tir-plate, .craps, or the waste cuttings of tin-plate, are utilized,'by converting them into or. in the'manufacture of cast-iron, or wroughtfiron, or steel.

The following is a description of the process, which will enable others acquainted with the artto which this my invention, pertains, to practisethe same.

I woric the shreds or scraps into compact ingots by rst twistingz,r them into a rope, by means of an apparatus shown ililiigure 1, of which A represents a rectangular bar of iron, having at one end a cone with an aperture proportionate-to the size of the rope to be made, and at' the 4opposite end a door or lid, B. The apex ofthe cone is formed into a hollow journal,

- and rests in a suitable box, while the opposite end is provided with a solid journal, which also rests in a proper journa1-box; the whole being so constructed that itwill ii'eely revolve by turning a crank, O, or, if desirable, by a belt over` a puliey.

Oppositethe aperture in thc couecnd, is a drum or windlass, E, turned by a crankand held to its place by a ratchet-wheel and pawl.

The shreds oftin-plate are put into thel box A, and the lid closed. At the aperture a small rope is formed by twisting. An implement, such as represented in Figure 3, may be used for that purpose; and the rope thus formed is drawn out ofthe box suiiiciently to attach it to the Windlass. The box is then made to l'evolve, which peribrins the twisting, while the wiudlass draws and coils the rope.

Before all the scraps have been removed from the box, it is rehlled, aud thus a continuons rope' is `formed.

The next step is to cutthe rope into pieces of, say, four vpounds each, amltoplace these sections in a mould, represented in Figure 2, consisting of `three sections, A B C. `A pistou or rammer is then emL ployed to force the scraps composing the rope compactly against section A. I preierfthe mouldto be cylindrical. The ingots thus forced will be about three inches in diameter, and weigh about four pounds each.

These ingots are enclosed in any suitable mould, as 4of sand, loam, 'or composition of clay and plumbag, and eight pounds of melted cast-iron are poured ou them, so as to permeate and rmly cement the mass together.

The proportion I havenamed. of castrou to the weight andsize of the plate ingot, is as small as I have. found economical; hut, of course,.alarger quam tity of iron may he added.

' Instead of pourinfel the molten iron on to the ingot Vin the mould, the ingot may be dipped once or several times in molten iron, and-a similar result will be obtained.

The ingots so prepared are melted in the cupola or other furnace, in the ordinary manner ot' melting castiron, or puddled inthe plnldling-furnace.

Having thus described my invention, and the manner in which the same is or may be carried-into effect, I would observe that I do'not wish to' be understood as claiming the mixing of waste masses of solid iron with molten iron, preparatory to remelting or reheating the conglomerate; nor yet, broadly, utilizing waste tin-scraps; but

\Vhat I do claim, is-

1. 'lle process herein described, ofutilizing the waste cuttings or scraps of tin-plate, by formingthe same into ingots, substantially as described, and sub jecting such ingots to the melting or puddling-process in any suitable furnace, as herein set forth.

2. The formation of interlaced masses of tin-scraps, preparatory to theirA beingr dipped in or mixed with molten cast-iron, substantially as set forth.

3. The production of ingots composed of waste tinscrapsnand cast-iron, substantially as herein set forth.

4. Theimethod' of and means herein described, for

producing4 skeleton -ingots of'waste tin-plate.

1n testimony whereof, I have signed my name to this specitication, before two subscribing witnesses. Witnesses: D. D. PAEMELEE.
